What is the Origin of Digital Chronobiology?

This term is a modern fusion of the established science of chronobiology, the study of biological rhythms, and the pervasive influence of digital technology. It specifically addresses the novel environmental pressures of artificial light exposure and information flow on the neuro-endocrine system, a concern nonexistent before the widespread adoption of screens.

What is the Mechanism of Digital Chronobiology?

Digital devices, particularly those emitting short-wavelength blue light, directly suppress the nocturnal secretion of melatonin by stimulating melanopsin-containing retinal ganglion cells, thereby disrupting the circadian rhythm. Furthermore, the constant stream of novel information and notifications can trigger an acute stress response, leading to inappropriate cortisol and catecholamine release late in the day, effectively shifting the body's internal clock and impairing sleep architecture.

Digital Chronobiology

Meaning

Digital Chronobiology is the emerging field that studies the interaction between modern digital device usage and the human body’s intrinsic circadian and ultradian rhythms. It focuses on how screen light exposure, notification patterns, and digital content consumption perturb the timing and amplitude of hormonal and physiological cycles. The clinical relevance lies in assessing and mitigating the chronodisruption caused by a digitally saturated lifestyle.
